REPAIR-SHEET.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed October 19, 1910. Serial 110. 588,438.

To all whom it may concern:

Be it known that I, THOMAS WHILDE, a citizen of the United States,residing at Bellingham, in the county of Whatcom and State of\Vashington, have invented certain new and useful Improvements inRepair- Sheets, of which the following is a specificasheet lead) andcoat this sheet on both sides with a solution made by dissolving rubberand gum asphaltum in carbon disulfid. A small quantity of pitch may beadded to the ingredients of the solution.

The figure in the accompanying drawing is a vertical sectlon through mynew repair sheet, the sheet-metal. base being indicated by a andthe'superimposed mixture or coating by b.

In using my new repair patch, the hole or fracture in the utensil to bemended is thoroughly cleaned of rust and the like; and the deterioratedmaterial around the-hole may be cut away to insure that the wall of thehole shall be strong enough to support the patch. A narrow strip is thencut from the latter and is rolled up into the form of a plug just largeenough to fill the hole well, with the ends of the plug projecting alittle. The utensil with the hole thus plugged is held over a lamp orother suitable source of heat, until the plug is so hot that it willgive forth a hissing sound when water is. applied to it in minutequantities, as with the wet finger. The utensil is now placed upon asuitable support, as a table, and pressure is applied to the, inside endof the plug, as by means of a damp thimble on the end of the finger. Asmooth finish may be given so that the-patch will not interfere with theuse of spoons, knives and the like. Under the influence of the heatapplied in repairing the utensil, the substances forming the coatingcombine to form a sort of cement; and the lug, when cooled, ispractically a solid rivet firmly adherent to the material of theutensil, a result which depends for its accomplishment upon the coat ingof the sheet metal on both sides as hereinbefore described. My newrepair patch has the advantage over solid plugs that the sheet may berolled to a size which will quite exactly fit the hole to be repaired,while solid plugs are made in only certain sizes. Moreover, a skilledmechanic is needed to insert a solid plug neatly and securely in placeand proper tools, such as a hammer or the like, are needed also. On theother hand, only light pressure, applied by the thimbleprotected fingerof an unskilled servant is needed to mend a utensil with my new repairpatch.

The coating on the metal sheet is in no sense a flux and there is noflux used in con 'neCtion with my new patch. Indeed, the
